My Carbon plenum is taking shape.I've got the top and bottom sections bonded.It needs some shaping and fettling but I'll be ableto start laying up the multiple layers of Carbon and Kevlarby the weekend.

I was going to hammer some heavy wall Ally tubing from round to rectangularfor each of the 8 runners.I did one and it was too time consuming and beyond my capabity so I decidedto produce molds and make the runners in Carbon.

The original is very smooth on the ID. I worked it with flapper wheels to a mirrorfinish. The OD has hammer marks etc so I'll use some filler and get to work.

We've all been there Mike. Brainstorming with others is a very valuable tool. They don't even have to understand what you're doing. Sometimes a totally different perspective brings out totally different ideas.

Thanks James and Pete. You're both so right!.My current design looks good but to actually produce the partsis a PITA.

I can go from the current 63mm ID on the round side to 80.That will make removing the part from the mold simple.Attaching the Carbon runners to the manifold creates anotherproblem so I was thinking of making a wooden buck and shapingthe parts (2) for each runner in Aluminium and get Dunc to weldthem.Nothing comes easy and I need to take a step back on this. PATIENCE!!!!!
